In the folklore of the Chiloé Island in southern Chile, the imbunche [im-boon-chay] is a legendary monster that protects the entrance to a warlock’s cave. According to legend, the Imbunche was a male child kidnapped by, or sold by his parents to a Brujo Chilote (a type of sorcerer or warlock of Chiloé).
The Brujo chilote transformed the child into a deformed hairy monster by breaking his legs and twisting them over his back, applying a magic cream over the boy’s to cause thick hairs and, finally splitting his tongue to produce a forked, snake-like, tongue.
